With Bioshock Infinite Burial at Sea "“ Episode Two coming next month, Irrational Games has announced today that the second downloadable episode will feature a new mode entitled "1998 Mode". In this mode, players will have to complete the episode using only non-lethal weapons and tools, making stealth the key to complete this challeging mode.

"In Burial at Sea "“ Episode Two we put a focus on balance and stealth mechanics. As we were developing this new style of gameplay, we started to see people self-impose non-lethal playthroughs. Given the fan reception of 1999 Mode, we thought it would be cool to give them another way to play Burial at Sea that challenged their mastery of stealth tools," said Ken Levine, creative director of Irrational Games.

Bioshock Infinite Burial at Sea "“ Episode Two Episode Two will be available for PS3, Xbox 360 and PC on the 25th of March. Season Pass owners will be able to downlaod the second episode for free, while purchased individually, the second episode will cost $14.99/£9.99.
